The presented results are the outcomes of wavelet analysis of layered maps of polarization azimuth and ellipticity for diffuse images of biological tissues with the following pathologies: myocardium - "ischemic heart disease (IHD) - acute coronary insufficiency (ACI)". The coordinate maps and linear profiles of multiscale wavelet coefficients are provided, which characterize the coordinate distributions of azimuth and ellipticity values of the multiply scattered object field of optically thick layers of biological tissues with different morphological structures and pathological conditions in the phase cross-section 𝜃 = 𝜋⁄8, where the influence of the diffuse component is minimized. Tables of statistical moments of 1st to 4th orders are presented, which characterize the distributions of amplitude values of multiscale wavelet coefficients for maps of polarization azimuth and ellipticity of diffuse microscopic images, and diagnostic levels of differentiation accuracy for various pathological conditions are revealed.
